WebHelium–neon laser at the University of Chemnitz, Germany. A helium–neon laser or He-Ne laser, is a type of gas laser whose high energetic medium gain medium consists of a mixture of 10:1 ratio of helium and neon at a total pressure of about 1 torr inside of a small electrical discharge. The best-known and most widely used He-Ne laser ... Web10 apr. 2024 · Laser-induced graphene (LIG) has attracted extensive attention owing to its facile preparation of graphene and direct engraving patterns for devices.
